Answer

MMCDLXXXIX

The correct answer is MMCDLXXXIX — Therefore, $2, 489$ in Roman numerals is $M M C D L X X X I X$ .

Step-by-step solution

Separate the number into place values: thousands $= 2000$ , hundreds $= 400$ , tens $= 80$ , units $= 9$ .
Convert each part using Roman symbols: $2000 = M M$ (since $M = 1000$ ).
$400 = C D$ (because $C$ before $D$ means $500 - 100$ ).
$80 = L X X X$ ( $L = 50$ and $X X X = 30$ ).
$9 = I X$ ( $I$ before $X$ means $10 - 1$ ).
Write the symbols in order from highest to lowest place value: $M M C D L X X X I X$ .
Combine them to get $M M C D L X X X I X$ .
Therefore, $2, 489$ in Roman numerals is $M M C D L X X X I X$ .

Common mistake: Writing

400

as

C C C C

instead of the correct subtractive form

C D

, or placing symbols in the wrong order.
